WIRE ROPE.

ments in Wire Ropes, of which the follow-` is a specification.

The present invention has more particularly reference to wire strands orropes, and has for its main object the production of a non-spinning ropeand the reduction of weer orgchaiing of the wires in the several layersof wires composing the strand or betweenthe strands composing the rope.

In wire ropes as at presen-t made thereV is considerable friction orchai-ing between the layers of wires when bending and passing oversheeres and drums. Furthermore in order'to prevent non-spinning of thestrand or rope when it is subjected to stresses, it has been customaryin the prior'art to twist or lay the several layers of the strandcr ropein opposite directions so that the spinning tendency of the two layerswill neutralize each other. When this construction or' the prior art isemployed the rope cannot be spliced, and also since the round wirescross each other at an angle, considerable friction lsind chaing occurs.Furthermore, in ropes of the prior art lit has not been possible totwist the strands of the rope i in the saine general direction as thedirec`4 tion of? twisting of the wires to prodiice the advantageousLang-lay rope, when it is desired to produce a non-spinning rope.

`The present invention consists in means interposed between one or morelayers of wires of the strand for preventing untwist- .ing rotation orspinning of the rope on strand when subjected to stresses Prefer-` ablythis is accomplished by interposing flat wires between the layers ofround. wires,A

whereby the inner and outer layers of wire will be locked together, asit were, .to.p 1'e vent rotation of the rope and to diminish the chatingaction of the round wires.

@ther features of the invention .will ap'- pear as the specicetionproceeds.

l'n the accompanying drawing the invention is illustrated in severalconcrete and preferred forms, but changes ofconstrue tion may he madewithout departing from the invention.

What is claimed, is

1. A wire strand composed of layers twisted wires of high tensilestrength, er layer of softer wires interposed between layers of hightensile strength wires. 2. A wire strand composedof a plurality oflayers of wires, said loyers having diiiien ent thrusts in the samelength, and a layer of softer metal wires interposed between thetirstmentiom=d` layers of wires.

3. A wire strand composed of e plnreiitL of layers of wires, said layersof wires crossstrandsbeing in the same general direction,

and a. layer of softer wire interposed between the several layers ofwires in each strand for preventing untwisting rotation when the ,rbpeissubjected to stresses.

5. A wire strand composed of a plurality of layers oftwisted wires, thewires in the several layers being laid in opposite directions, andsofter wiresinterposed between the several layers of wires forpreventing un twisting rotation of the strand when it is subjected tostresses.

A6. A wire rope composed yof a' plurality of twisted strands, eachstrand having a plurality of layers of twistedwires, the wires in theseveral layers being laid. in opposite direotions, and a layer of'softer wire inter-v posed between the several'lyers of wires in eachstrand for preventing Iuntwisting rotation when the rope is subjected tostresses'.

7. A wire rope composed of a'plurality'of twisted strands, each strandhaving a plurality of layers of twisted wires, the 'wires in, theseveral layers being laid in opposite di .rection'sthe twist of theouter layer of wires and the twist of the strands being in the sainegeneral direction and a layer oi softer inet-al interposed between theseveral layers oi' wires in each strand -for preventing untwistingrotation when the rope is subjected to stresses.
